Cloud Foundry is proving itself to be truly the foundry for creating entirely new cloud offerings:

ActiveState is building a cloud for Python and Django and contributing code to support Python back to the Cloud Foundry open source project.

Appfog is building a cloud for PHP developers and contributing code to support PHP back to the Cloud Foundry open source project

The beauty of this is that innovative startups are able to start with a scalable cloud "stack" that gives them a multi-language PaaS without locking them into a particular cloud provider.

So for example, Appfog gets to use Cloud Foundry's best in class PaaS services and then target deployment to Amazon's EC2 and services like S3. Appfog CEO Lucas Carlson blogged here about how standing on the shoulders of cloud computing giants will allow Appfog to win in the cloud by providing the most compelling user experience.

Expect to see the pace of innovation accelerate dramatically going forward!
